目的 了解严重急性呼吸综合症(SARS)病人的流行病学,明确其感染、传播和持续的过程及变量,为制定恰当的公共关系干预措施提供依据;探讨流行病学的某些因素与临床病情轻重及转归的关系。方法 用回顾性统计分析的方法对入院的109例SARS病例的流行病学及临床资料进行总结。结果 109例SARS病例潜伏期为2～14天,平均为6.9±2.8天。有66.0％的患者与原SARS患者有密切接触史或明确传染他人,呈家族及医务人员聚集现象。传播途径为近距离飞沫和密切接触。结论 ARS是一种严重的传染病,死亡率较高,但是切断传染源是可以预防的。
Objective To understand the epidemiology of patients with severe acute respiratory syndrome (SARS) and to identify the processes and variables of infection, transmission and persistence, and to provide a basis for formulating appropriate public relations interventions. To explore some epidemiological factors and clinical conditions Severity and outcome of the relationship. Methods The retrospective statistical analysis of 109 cases of SARS admitted to the epidemiological and clinical data were summarized. Results The 109 SARS cases had an incubation period of 2-14 days with an average of 6.9 ± 2.8 days. 66.0% of the patients had close contact with the original SARS patients or had a clear contagion of others, showing the phenomenon of family and medical staff gathering. Transmission routes for the close-range droplets and close contact. Conclusion ARS is a serious infectious disease with a high mortality rate, but cutting off the source of infection is preventable.
